Here's the deal: I've always liked the hood scoop look, and I've seen a Blazer rolling around NCSU's campus that has the ram air hood like this:

They run upwards of $300, unpainted. So that's quite expensive for a strictly appearance item. So my question is...is there anyway to re-do the entire intake to make a true ram air style intake? If I'm going to spend 300 on a hood, I'd rather have it do something for me..

A few problems I've already thought of:

-With the shorter intake, the air could be much more turbulent...but if the hole under the scoop is at the back...it could stabilize somewhat?
-Relocating the MAF in such a short track and making it actually effective
-If this is the main intake...how would I keep debris and water out...I know WRXs have an air cleaner element in the scoop...but would this be effective?
-Can I even suck enough air through the hood to fuel the engine?

Thoughts anyone? Solutions? Feel free to shoot the idea down, but gimmie a reason why if it won't work

Also if the ram air idea won't work...is there any benefit to making it a true scoop just to help cool the engine compartment? Or would I need vents at the wiper cowl to get the hot air out as cool air comes in...

It might be easier to set up with a body lift on..give a little more room to put in some piping and wiring up the MAF...the engine does stay put while the fenders go up with a body lift right...

i dont know how much you know about old school real muscle cars but i have a 1969 GTO Judge with ram air. theres a knob you pull to open the scoops on the hood to let air in and pontiac claimed it added 5 hp. the only thing i can think of is a 80's model camaro/vette that had the flat filter in the front and somehow put that under/behind the scoop.

So those old muscle cars used the scoop as a secondary air intake...hrm...and I'm guessing it was up to the driver not to pull the knob if it was raining or snowing or what not..then the filter for physical debris on a nice day..

The WRX has a simillar flat filter just under the intake...I'll try looking on some Suburu forums...see if I can't figure out how their intake is run (scoop as a secondary or what)

Edit: Talked to a few guys on a WRX forum, found out the WRX uses the hood scoop to cool the top mounted intercooler for their turbo. They said the same thing, the older ram jet pontiacs and camaros used a true hood scoop, but with a rod to control opening.

An idea was suggested to setup a Y pipe, and simply relocate the MAF closer to the throttle body to allow the hood scooped air to pass through the MAF. Thoughts?

actually pontiac referred to it as ram air. there is a air tight rubber seal that is on top of the air filter housing and the bottom of the hood. the driver decided when to pull the knob to open it up. chevelles/camaros had a cowl air hood that worked off vaccum and sucked in cold air in from the base of the windshield ( lower air pressure made it easier to take in the air ). dodge had something as well. what i was suggesting is finding a sir filter like on this site ( camaro/vette sir intake ) to put under the scoop. routing it might be a little diffrent but it can be done. http://images.google.com/imgres?imgurl=http://img.nextag.com/image/1998-2002-Chevy-Camaro/0/000/005/196/793/519679301.jpg&imgrefurl=http://www.nextag.com/camaro-intake/search-html&h=75&w=75&sz=3&hl=en&start=8&um=1&tbnid=l9fksBahMD9U-M:&tbnh=71&tbnw=71&prev=/images%3Fq%3D1989%2Bcamaro%2Bair%2Bintake%2Bbox%26um%3D1%26hl%3Den%26client%3Dfirefox-a%26rls%3Dorg.mozilla:en-US:official%26sa%3DN

im sure you can find a stock air box off a camaro/vette in a bone yard or ebay for cheaper and add the air filter ( these boxes were used in the late 80's but im not sure when they started or ended ) that should give ya a good start.
